Assumptions and estimates

  • Annualised return treats all net proceeds as received at the end. Multiple cash-flow dates require an IRR calculation. Tax and financing are excluded unless included in costs.
  • Method: ROI = net profit ÷ initial investment. Annualised return treats net proceeds as an end-of-period value.
  • The model is not IRR for multiple cash-flow dates. Include relevant tax and fees in costs.
